HELLP syndrome is a severe complication of pregnancy associated with severe preeclampsia, though it can occasionally develop without high blood pressure or proteinuria. The acronym stands for Hemolysis (H), Elevated Liver enzymes (EL), and Low Platelet count (LP).
This cascade stems from systemic endothelial dysfunction and vasospasm, creating a dangerous multi-organ threat for both mother and fetus.
The clinical picture of HELLP syndrome can be deceptive because symptoms frequently mimic common, benign discomforts of late pregnancy. Midwives must maintain a high index of suspicion. Patients frequently complain of right upper quadrant or epigastric pain, which is caused by stretching of Glisson's capsule around the liver. Nausea, vomiting, and extreme fatigue are also common early warning signs.
Diagnosis relies primarily on laboratory blood investigations rather than blood pressure readings alone. Complete blood counts reveal microangiopathic hemolytic anemia with schistocytes on a peripheral blood smear and a low platelet count. Liver function tests show markedly elevated AST and ALT levels. Serum lactate dehydrogenase rises due to red blood cell destruction. A diagnosis is established when all three components of the syndrome are present, though partial variants also demand urgent intervention.
Once HELLP syndrome is identified, stabilization must happen rapidly in a tertiary care setting. The primary goals are preventing maternal seizures, controlling dangerously high blood pressure, and correcting severe clotting abnormalities.
Fluid balance must be carefully monitored because damaged capillary membranes put these patients at high risk for pulmonary edema.
Delivery is the definitive cure for HELLP syndrome. Pregnancy prolongation is rarely safe once the diagnosis is confirmed, regardless of gestational age.
If the pregnancy has reached 34 weeks gestation or beyond, or if there is evidence of fetal distress, liver infarction, renal failure, or suspected placental abruption, delivery is expedited immediately. For gestations between 24 and 34 weeks, a brief delay of 24 to 48 hours may be considered solely to administer corticosteroids for fetal lung maturation, provided the maternal condition remains stable under intensive monitoring.
The mode of delivery depends on cervical favorability, gestational age, and coagulation status. Cesarean section is often necessary if the cervix is unfavorable and the platelet count is critically low, provided adequate blood products are available to cover the surgical intervention.
The danger does not end with the birth of the baby. The postpartum period is a high-risk window because HELLP syndrome can temporarily worsen before it begins to improve. Midwives must continue magnesium sulfate infusions for at least 24 hours after delivery to prevent postpartum eclampsia.
Laboratory values—particularly platelet counts and liver enzymes—must be monitored daily until they show a clear upward and resolving trend. Coagulation profiles help track recovery. Midwives must remain vigilant for life-threatening complications such as subcapsular liver hematoma rupture, acute kidney injury, and postpartum hemorrhage due to underlying thrombocytopenia. Patient education on warning signs such as persistent headache, visual changes, or right upper quadrant pain is vital before discharge.
